+ * An Interval object represents a half-open interval of time, where each endpoint is a {@link DateTime}. Conceptually, it's a container for those two endpoints, accompanied by methods for creating, parsing, interrogating, comparing, transforming, and formatting them.
+ *
+ * Here is a brief overview of the most commonly used methods and getters in Interval:
+ *
+ * * **Creation** To create an Interval, use {@link fromDateTimes}, {@link after}, {@link before}, or {@link fromISO}.
+ * * **Accessors** Use {@link start} and {@link end} to get the start and end.
+ * * **Interrogation** To analyze the Interval, use {@link count}, {@link length}, {@link hasSame}, {@link contains}, {@link isAfter}, or {@link isBefore}.
+ * * **Transformation** To create other Intervals out of this one, use {@link set}, {@link splitAt}, {@link splitBy}, {@link divideEqually}, {@link merge}, {@link xor}, {@link union}, {@link intersection}, or {@link difference}.
+ * * **Comparison** To compare this Interval to another one, use {@link equals}, {@link overlaps}, {@link abutsStart}, {@link abutsEnd}, {@link engulfs}.
+ * * **Output** To convert the Interval into other representations, see {@link toString}, {@link toISO}, {@link toISODate}, {@link toISOTime}, {@link toFormat}, and {@link toDuration}.
